The Michelin Red Guide has historically had many more listings than its rivals, relying on an extensive system of symbols to describe each establishment in as little as two lines. Restaurants rated with a star also listed three specialities. Recently, however, very short summaries (2-3 lines) have been added for many establishments, for example 9,000 in France. These short summaries are written in the language of the country for which it is published, but the symbols are universal. The Red Guide uses anonymous inspections and does not charge for entries. Michelin claims to revisit establishments on average once every eighteen months in order to keep ratings up to date.There is a Green Guide for each French region and many countries, regions, and cities outside France. Most Green Guides on France are available in several languages. They include background information and an alphabetical section describing points of interest. Like the Red Guide, they use a three-star system for recommending sights.
